In August 2015, Lessig announced that he was exploring a possible candidacy for President of the United States, promising to run if his exploratory committee raised $1 million by Labor Day.[8][9] After accomplishing this, on September 6, 2015, Lessig announced that he was entering the race to become a candidate for the 2016 Democratic Party's presidential nomination.[10] Lessig has described his candidacy as a referendum on campaign finance reform and electoral reform legislation. He stated that, if elected, he would serve a full term as president with his proposed reforms as his legislative priorities.[11] He ended his campaign in November 2015, citing rule changes from the Democratic Party that precluded him from appearing in the televised debates.[12][13]

Lessig returned to Harvard in July 2009 as professor and director of the Edmond J. Safra Center for Ethics.[17] In 2013, Lessig was appointed as the Roy L. Furman Professor of Law and Leadership; his chair lecture was titled "Aaron's Laws: Law and Justice in a Digital Age."[18][19]

Lessig has been politically liberal since studying philosophy at Cambridge in the mid-1980s. By the late 1980s, two influential conservative judges, Judge Richard Posner and Justice Antonin Scalia, selected him to serve as a law clerk, choosing him for his supposed "brilliance" rather than for his ideology and effectively making him the "token liberal" on their staffs.[21] Posner would later call him "the most distinguished law professor of his generation."[22]

Lessig has emphasized in interviews that his philosophy experience at Cambridge radically changed his values and career path. Previously, he had held strong conservative or libertarian political views, desired a career in business, was a highly active member of Teenage Republicans, served as the Youth Governor for Pennsylvania through the YMCA Youth and Government program[23] in 1978, and almost pursued a Republican political career.

What was intended to be a year abroad at Cambridge convinced him instead to stay another two years to complete an undergraduate degree in philosophy and develop his changed political values. During this time, he also traveled in the Eastern Bloc, where he acquired a lifelong interest in Eastern European law and politics.

Lessig remains skeptical of government intervention but favors some regulation, calling himself "a constitutionalist." On one occasion, Lessig also commended the John McCain campaign for discussing fair use rights in a letter to YouTube where it took issue with YouTube for indulging overreaching copyright claims leading to the removal of various campaign videos.[24]

In computer science, "code" typically refers to the text of a computer program (the source code). In law, "code" can refer to the texts that constitute statutory law. In his 1999 book Code and Other Laws of Cyberspace, Lessig explores the ways in which code in both senses can be instruments for social control, leading to his dictum that "Code is law." Lessig later updated his work in order to keep up with the prevailing views of the time and released the book as Code: Version 2.0 in December 2006.

Lessig has been a proponent of the remix culture since the early 2000s.[25] In his 2008 book Remix[26][27] he presents this as a desirable cultural practice distinct from piracy. Lessig further articulates remix Culture as intrinsic to technology and the Internet. Remix culture is therefore an amalgam of practice, creativity, "read/write" culture and the hybrid economy.

According to Lessig, the problem with the remix comes when it is at odds with stringent US copyright law. He has compared this to the failure of Prohibition, both in its ineffectiveness and in its tendency to normalize criminal behavior. Instead he proposes more lenient licensing, namely Creative Commons licenses, as a remedy to maintain "rule of law" while combating plagiarism.[28]

In March 2006, Lessig joined the board of advisors of the Digital Universe project.[33] A few months later, Lessig gave a talk on the ethics of the Free Culture Movement at the 2006 Wikimania conference. In December 2006, his lecture On Free, and the Differences between Culture and Code was one of the highlights at 23C3 Who can you trust?.[34]

Lessig claimed in 2009 that, because 70% of young people obtain digital information from illegal sources, the law should be changed.[35]

In a foreword to the Freesouls book project, Lessig makes an argument in favor of amateur artists in the world of digital technologies: "there is a different class of amateur creators that digital technologies have ... enabled, and a different kind of creativity has emerged as a consequence."[36]

Lessig has long been known to be a supporter of net neutrality. In 2006, he testified before the US Senate that he believed Congress should ratify Michael Powell's four Internet freedoms and add a restriction to access-tiering, i.e. he does not believe content providers should be charged different amounts. The reason is that the Internet, under the neutral end-to-end design is an invaluable platform for innovation, and the economic benefit of innovation would be threatened if large corporations could purchase faster service to the detriment of newer companies with less capital. However, Lessig has supported the idea of allowing ISPs to give consumers the option of different tiers of service at different prices. He was reported on CBC News as saying that he has always been in favour of allowing internet providers to charge differently for consumer access at different speeds. He said, "Now, no doubt, my position might be wrong. Some friends in the network neutrality movement as well as some scholars believe it is wrong—that it doesn't go far enough. But the suggestion that the position is 'recent' is baseless. If I'm wrong, I've always been wrong."[37]

Despite presenting an anti-regulatory standpoint in many fora, Lessig still sees the need for legislative enforcement of copyright. He has called for limiting copyright terms for creative professionals to five years, but believes that creative professionals' work, many of them independent, would become more easily and quickly available if bureaucratic procedure were introduced to renew trademarks for up to 75 years after this five-year term.[38]
Lessig has repeatedly taken a stance that privatization through legislation like that seen in the 1980s in the UK with British Telecommunications is not the best way to help the Internet grow. He said, "When government disappears, it's not as if paradise will take its place. When governments are gone, other interests will take their place," "My claim is that we should focus on the values of liberty. If there is not government to insist on those values, then who?" "The single unifying force should be that we govern ourselves."[39]

In March 2003, Lessig acknowledged severe disappointment with his Supreme Court defeat in the Eldred copyright-extension case, where he unsuccessfully tried to convince Chief Justice William Rehnquist, who had sympathies for de-regulation, to back his "market-based" approach to intellectual property regulation.[44]

In August 2013, Lawrence Lessig brought suit against Liberation Music PTY Ltd., after Liberation issued a takedown notice of one of Lessig's lectures on YouTube which had used the song "Lisztomania" by the band Phoenix, whom Liberation Music represents.[45][46] Lessig sought damages under section 512(f) of the Digital Millennium Copyright Act, which holds parties liable for misrepresentations of infringement or removal of material.[47] Lessig was represented by the Electronic Frontier Foundation and Jones Day.[48] In February 2014, the case ended with a settlement in which Liberation Music admitted wrongdoing in issuing the takedown notice, issued an apology, and paid a confidential sum in compensation.[49][50]

In October 2014, Killswitch, a film featuring Lawrence Lessig, as well as Aaron Swartz, Tim Wu, and Edward Snowden received its World Premiere at the Woodstock Film Festival, where it won the award for Best Editing. In the film, Lessig frames the story of two young hacktivists, Swartz and Snowden, who symbolize the disruptive and dynamic nature of the Internet. The film reveals the emotional bond between Lessig and Swartz, and how it was Swartz (the mentee) that challenged Lessig (the mentor) to engage in the political activism that has led to Lessig's crusade for campaign finance reform.[51][52]

In February 2015, Killswitch was invited to screen at the Capitol Visitor's Center in Washington DC by Congressman Alan Grayson. The event was held on the eve of the Federal Communications Commission's historic decision on Net Neutrality. Lessig, Congressman Grayson, and Free Press (organization) CEO Craig Aaron spoke about the importance of protecting net neutrality and the free and open Internet.[53][54]

Congressman Grayson states that Killswitch is "One of the most honest accounts of the battle to control the Internet -- and access to information itself.".[53]Richard von Busack of the Metro Silicon Valley, writes of Killswitch, "Some of the most lapidary use of found footage this side of The Atomic Café".[51] Fred Swegles of the Orange County Register, remarks, "Anyone who values unfettered access to online information is apt to be captivated by Killswitch, a gripping and fast-paced documentary."[52] Kathy Gill of GeekWire asserts that "Killswitch is much more than a dry recitation of technical history. Director Ali Akbarzadeh, producer Jeff Horn, and writer Chris Dollar created a human centered story. A large part of that connection comes from Lessig and his relationship with Swartz."[55]

At the iCommons iSummit 07, Lessig announced that he would stop focusing his attention on copyright and related matters and work on political corruption instead, as the result of a transformative conversation with Aaron Swartz, a young internet prodigy whom Lessig met through his work with Creative Commons.[57] This new work was partially facilitated through his wiki, Lessig Wiki, which he has encouraged the public to use to document cases of corruption.[58] Lessig criticized the revolving door phenomenon in which legislators and staffers leave office to become lobbyists and have become beholden to special interests.[59]

Despite having decided to forgo running for Congress himself, Lessig remained interested in attempting to change Congress to reduce corruption.[61] To this end, he worked with political consultant Joe Trippi to launch a web based project called "Change Congress".[62] In a press conference on March 20, 2008, Lessig explained that he hoped the Change Congress website would help provide technological tools voters could use to hold their representatives accountable and reduce the influence of money on politics.[63] He is a board member of MAPLight.org, a nonprofit research group illuminating the connection between money and politics.

Change Congress later became Fix Congress First, and was finally named Rootstrikers.[64][65] In November 2011, Lessig announced that Rootstrikers would join forces with Dylan Ratigan's Get Money Out campaign, under the umbrella of the United Republic organization.[66][67] Rootstrikers subsequently came under the aegis of Demand Progress, an organization co-founded by Aaron Swartz.

In 2010, Lessig began to organize for a national Article V convention.[68] He co-founded Fix Congress First! with Joe Trippi.[69] In a speech in 2011, Lessig revealed that he was disappointed with Obama's performance in office, criticizing it as a "betrayal", and he criticized the president for using "the (Hillary) Clinton playbook".[70] Lessig has called for state governments to call for a national Article V convention,[71] including by supporting Wolf PAC, a national organization attempting to call an Article V convention to address the problem.[72] The convention Lessig supports would be populated by a "random proportional selection of citizens" which he suggested would work effectively. He said "politics is a rare sport where the amateur is better than the professional."[71] He promoted this idea at a September 24–25, 2011, conference he co-chaired with the Tea Party Patriots' national coordinator,[73] in Lessig's October 5, 2011, book, Republic, Lost: How Money Corrupts Congress—and a Plan to Stop It,[74] and at the Occupy protest in Washington, DC.[75] Reporter Dan Froomkin said the book offers a manifesto for the Occupy Wall Street protestors, focusing on the core problem of corruption in both political parties and their elections.[76] An Article V convention does not dictate a solution, but Lessig would support a constitutional amendment that would allow legislatures to limit political contributions from non-citizens, including corporations, anonymous organizations, and foreign nationals, and he also supports public campaign financing and electoral college reform to establish the one person, one vote principle.[77]

The New Hampshire Rebellion is a walk to raise awareness about corruption in politics.[78] The event began in 2014 with a 185-mile march in New Hampshire.[79] In its second year the walk expanded to include other locations in New Hampshire.[80]

From January 11 to 24, 2014, Lessig and many others, like New York activist Jeff Kurzon, marched from Dixville Notch, New Hampshire to Nashua (a 185-mile march) to promote the idea of tackling "the systemic corruption in Washington".[citation needed] Lessig chose this language over the related term "campaign finance reform," commenting that "Saying we need campaign finance reform is like referring to an alcoholic as someone who has a liquid intake problem."[citation needed] The walk was to continue the work of NH Native Doris "Granny D" Haddock, and in honor of deceased activist Aaron Swartz.[78] The New Hampshire Rebellion marched 16 miles from Hampton to New Castle on the New Hampshire Seacoast.[81] The initial location was also chosen because of its important and visible role in the quadrennial "New Hampshire primaries", the traditional first primary of the presidential election.[81]

Lessig announced the launch of his presidential campaign on September 6, 2015.
On August 11, 2015, Lessig announced that he had launched an exploratory campaign for the purpose of exploring his prospects of winning the Democratic Party's nomination for President of the United States in the 2016 election.[9][82] Lessig pledged to seek the nomination if he raised $1 million by Labor Day 2015.[82] The announcement was widely reported in national media outlets, and was timed to coincide with a media blitz by the Lessig 2016 Campaign. Lessig was interviewed in The New York Times and Bloomberg. Campaign messages and Lessig's electoral finance reform positions were circulated widely on social media.[82][83] His campaign was focused on a single issue: The Citizen Equality Act, a proposal that couples campaign finance reform with other laws aimed at curbing gerrymandering and ensuring voting access.[82] As an expression of his commitment to the proposal, Lessig initially promised to resign once the Citizen Equality Act became law and turn the presidency over to his vice president, who would then serve out the remainder of the term as a typical American president and act on a variety of issues. In October 2015, Lessig abandoned his automatic resignation plan and adopted a full policy platform for the presidency, though he did retain the passage of the Citizen Equality Act as his primary legislative objective.[82]

In 2011, Lessig was named to the Fastcase 50, "honoring the law's smartest, most courageous innovators, techies, visionaries, and leaders."[87] Lessig was awarded honorary doctorates by the Faculty of Social Sciences at Lund University, Sweden in 2013 and by l'Université Catholique de Louvain in 2014.[88][89] Lessig received the 2014 Webby Lifetime Achievement award for co-founding Creative Commons and defending net neutrality and the free and open software movement.[90]

In May 2005, it was revealed that Lessig had experienced sexual abuse by the director at the American Boychoir School, which he had attended as an adolescent.[93] Lessig reached a settlement with the school in the past, under confidential terms. He revealed his experiences in the course of representing another student victim, John Hardwicke, in court.[94] In August 2006, he succeeded in persuading the New Jersey Supreme Court to restrict the scope of immunity radically, which had protected nonprofits that failed to prevent sexual abuse from legal liability.[95]

Lessig is married to Bettina Neuefeind, a German-born Harvard University colleague. The two married in 1999.[96] He and Neuefeind have three children: Willem, Teo, and Tess.[97]

Lessig said about this appointment: "Did Justice Jackson pick me to be his special master because he had determined I was the perfect mix of Holmes, and Ed Felten? No, I was picked because I was a Harvard Law Professor teaching the law of cyberspace. Remember: So is 'fame' made."[100]
